Text to schematic
Turn a plain-English description into a validated schematic
Describe the circuit you want in one or two sentences. Banana Board works out the connections, checks them against the target board's real pins, and produces a wiring diagram, a pin-by-pin map, and a netlist you can open in KiCad as an editable schematic and PCB.
A real board derived at page-build time: placed, routed on two layers, and graded. Every chip (grade, DRC, copper length, vias) is a number the engine computed, not a claim.
What “text to schematic” means here
Most “AI schematic” tools draw a picture that looks plausible and hope the wires are right. Banana Board works at the connection level: it decides which component pin connects to which board pin, then represents that as a clear wiring diagram, a pin-by-pin table, and a netlist. Because the output is a real netlist rather than an image, it carries the actual electrical intent forward — into simulation, into a routed PCB, and into KiCad where it opens as an editable schematic and board you can keep refining.
Why the connections are checked, not guessed
Before you see anything, every connection is validated against the target board's verified pin map and run through electrical-rule checks: power and ground integrity, two outputs driving the same net, input-only and strapping pins used incorrectly, and ADC channel availability. A power budget confirms the board can actually source what the design draws. That is the difference between a schematic that compiles in your head and one that survives contact with a soldering iron.
From schematic to a board you can order
The same netlist places and routes a real 2-layer PCB, design-rule-checks the copper, and exports order-ready Gerbers with a drill file, mask and silkscreen layers, and a bill of materials with distributor links. Prefer to finish the layout by hand? Export the whole project to KiCad. Nothing is a dead end — the schematic is the start of a manufacturable board, not a screenshot.
Vibe-design your PCB
Describe the board in plain English. Banana Board places the parts, routes the copper on two layers, checks it against the netlist, and hands you fab-ready Gerbers.
Frequently asked
Can AI generate a schematic from a text description?
Yes. Describe the circuit in plain English and Banana Board determines the connections, validates them against the board's real pins, and produces a wiring diagram, a pin-by-pin map, and a netlist. You can export that to KiCad, where it becomes a fully editable schematic and PCB.
What is the difference between a wiring diagram and a schematic?
A wiring diagram shows physical connections between parts and board pins, which is the clearest view when you are building on a breadboard or perfboard. A schematic is the symbol-based electrical drawing used in EDA tools. Banana Board generates the validated wiring and netlist, and exporting to KiCad gives you the symbol schematic and a PCB you can edit.
Is the generated netlist checked for errors?
Yes. Every connection is checked against the target board's verified pin map and run through electrical-rule checks (power, ground, double-drive, input-only pins, strapping pins, and ADC availability) plus a power budget, before you see the result.
Can I export the schematic to KiCad?
Yes. The whole project exports to KiCad so you can keep editing the schematic and refining the board layout in a full EDA tool, or hand it to a colleague who prefers one.
Which boards and parts are supported?
Arduino Uno, Nano, Mega, and Leonardo; ESP32 DevKit, C3, and S3; ESP8266 NodeMCU; and the Raspberry Pi Pico, Pico W, and Nano RP2040 Connect, plus common sensors, drivers, and displays, each validated against the board's real pin map.
Is it free?
There is a free tier, so you can describe a circuit and get a validated schematic and board without paying. You only pay a board house when you decide to manufacture.
Build it, do not just look it up
Describe your circuit in one sentence and Banana Board wires it to these exact pins, validates it, and lays out a fab-ready PCB.
